先按显示屏下面左上SHIFT一下,再找到右边中间偏下的AC按一下,关机搞定。
1.卡西欧科学计算器和普通计算器一样,能够正常使用各个符号进行计算;

2.卡西欧计算器除了每个键的使用外,还有第二功能,大部分按键上方都有符号、字母等黄色字体,这些字体就是计算器每个对应按钮的第二功能。

3.其中要启用第二功能那就需要了解计算器上一个很重要的功能键SHIFT;

4.使用第二功能的时候,都需要先按SHIFT键,这个时候屏幕上会显示一个S,这就说明第二功能打开了。

5.按了SHIFT以后,再按想输入的符号,就相当于电脑键盘的SHIFT键一样。例如,先按SHIFT,再按平方根,这样就能计算平方根结果。
